WT
Parameter Range: (00-15)
“WT” sets the wire tension on machines equipped with an auto wire threader. If the
setting is at zero, then the machine uses the knob on the control to set the tension amount.
If a value is set in the WT parameter, then it uses that value to set tension (ignoring the
knob). Please note, the knob value wouldn’t match the setting you would use for the WT
parameter. Refer to the introduction of the cutting condition manual for a comparable
setting.
WS
Parameter Range: (00-15)
“WS” sets the wire speed on machines equipped with an auto wire threader. If the setting
is at zero, then the machine uses the knob on the control to set the tension amount. If a
value is set in the WS parameter, then it uses that value to set wire speed (ignoring the
knob). Please note, the knob value wouldn’t match the setting you would use for the WS
parameter. Refer to the introduction of the cutting condition manual for a comparable
setting.

Before writing a program, you must determine the required cutting conditions and offsets
to use by looking in the cutting condition manual. Sodick has done much of the research
required to develop cutting conditions and offsets. To get the proper conditions and
offsets, all you will have to do is select from list in the cutting condition manual. Using a
“C” code and “H” code in your program does this.
The condition manual will give you Sodick’s recommended conditions and offsets that
you will need to enter into the program. The “C” codes that the manual makes reference
to are loaded into the machines memory when it boots up. The cutting condition file’s
name is “COND.DAT”, and can be viewed in the EDIT screen.
To program a part, you must know the conditions and offsets (C and H codes)required to
produce the cut to your requirements. The condition manual from Sodick is broken down
into four basic categories to help you find the proper conditions and offsets.
1) Wire Diameter. After you select the wire diameter you wish to use, you will reference
the condition manual to find the proper pages for the wire diameter you selected.
2) Workpiece Material. Under each wire diameter available, there are several materials
to choose from.
3) Workpiece Thickness. Each material listed will allow you to choose from several
different workpiece thickness.
